Deploying .NET Framework 4.5.2 as a Package/Program has always been a possibility, and now it can even be deployed with Software Update Management as a feature pack. But, since the .NET Framework’s only purpose is to support other applications, it makes a lot of sense to be able to deploy it using the Application Model in Configuration Manager. This means the .NET Framework can be defined as a prerequisite for another application. Having .NET Framework 4.5.2 ready to go as an application means any requirement can be covered .NET Framework 4 or above.
